Recipe: Sweet Potato Gratin

Sweet Potato Gratin
Precooked sweet potatoes can go into a slow cooker with gobs of sugar and marshmallows, but I have never been a fan. I far prefer them with just a little sweetening so it’s possible to really enjoy their natural flavor.

Serves 6 or more

1 tablespoon unsalted butter

2 pounds sweet potatoes, peeled and grated

1 tangy apple, such as Granny Smith, peeled and grated

1 tablespoon turbinado sugar (divided use)

1 teaspoon kosher salt or coarse sea salt

1/2 teaspoon crumbled dried sage

Freshly ground black pepper

1 cup heavy cream Fresh sage leaves, for garnish (optional)

Generously butter the inside of the slow cooker. Leave excess butter in the bottom.

In a mixing bowl, combine the sweet potatoes, apple, 2 teaspoons of sugar, salt, sage, and several grinds of pepper. Pat mixture into the slow cooker. Pour cream over it. Sprinkle the remaining teaspoon of sugar over the top. Cover and cook 4–5 hours on low, until sweet potatoes are very tender.
